Object: Postural balance in normal patients and in patients with lumbar osteochondrosis. Objective: To establish functionality and compensatory changes in postural balance system based on clinical and radiographic examination of the vertical posture regulation mechanisms in normal patients and in patients with lumbar osteochondrosis. Methods: Clinical, radiographic, radiometric, including bio-mechanical using computerized electro-goniometer SpinalMouse (Idiag, Voletswil, Switzerland) and platform statografa, electrophysiological, and statistical. For the first time it was found that a significant prevalence of asymmetry in the articular cartilages and transverse processes, incongruency in articular facets, and the rotation of the spinous processes in patients with severe lumbar osteochondrosis and in those with hidden antalgic scoliosis compared with volunteers and in patients with symmetric hypertonic paravertebral muscles.For the first time found that spinal-pelvic balance is adjusted: 1) At the location of the line of gravity in the lumbosacral disk space - at the expense of the ideal ratio "spine balance" with "pelvic balance" with the positional settings of the hip joints; 2) For shifting the line of gravity in front - by the perfect position with the position of the hip joints bend of the trunk.

For the first time identified the mechanisms of postural balance regulation: 1) for ergonomic options - due to asymmetry in the frontal vertical position with the position relaxing the muscles of the lumbar-pelvic and lower limb unloaded; 2) when biomechanically discordant versions - by a substantial tightening of the kinematic chain links of the spine - pelvis - hip joints with internally set the reference junctions. For the first time shown that the asymmetry of the rear supporting elements of the complex significantly affects the level of the bioelectrical activity of the paravertebral muscles, duration catamnesis, sharpness debut and frequency of relapses in patients with lumbar osteochondrosis. Refined versions of spine and pelvic balance in asymptomatic subjects, as well as variants of myotonic reactions of paravertebral muscles in patients with lumbar osteochondrosis. We developed and put into practice a new method of diagnosis of the functional state of the musculoskeletal system (patent of Ukraine for utility model number 71927), allowing identification of functionally advantageous variants of the vertical posture (with lumbosacral disc area of the passage of the line of gravity), and uncompensated postural imbalance (with rear offset line of gravity), potentiating prolong pain and progression of the disease. We developed and put into practice a new method of assessment of sagittal spinal-pelvic balance, on the basis of which identified potential decompensated version of imbalance with the passage of the projection OCM behind the sacrum. These results are objectified degree of adaptation of the locomotor apparatus of the patient to the industrial and domestic loads with medical and social expertise, as well as give an opportunity to develop a technique of selective stages of physiotherapy in medical rehabilitation. We developed and put into practice guidelines for the diagnosis of changes of the kinematics of the lumbar segments and lumbar-pelvic rhythm complementary assessment of functionality of the spine in patients with lumbar osteochondrosis antalgia and degenerative spinal deformities. Developed and put into practice guidelines for the diagnosis of changes stabilography parameters specifying the functional evaluation of the musculoskeletal system in patients with lumbar osteochondrosis.
